3 Claims.

This invention relates to a tie for tying partitions to a wall or ceiling, the object being to provide a construction which may be quickly and easily secured to a wall or ceiling in a way to readily cooperate with a partition for locking the parts together.

Another object is to provide a tie which is formed with foraminous metal strips and securing means with the parts so formed that the mortar will interlock with the tie member and with the edge of the partition.

A further object, more specifically, is to provide a tie member for tying partitions to a wall or ceiling wherein the tie member is formed of a foraminous strip of sheet metal having a longitudinally positioned raised portion or head.

In the accompanying drawing:

Fig. 1 is a fragmentary view partly in section showing part of a partition together with a part of a vertical wall and a part of a ceiling together with a tie embodying the invention arranged in operative position;

Fig. 2 is a sectional view through Fig. 1 approximately on the line 22, the same being on an enlarged scale;

Fig. 3 is an elevation of a short section of a foraminous strip disclosing certain features of the invention.

In office buildings and other buildings it becomes necessary from time to time to build comparatively thin partitions to divide the floor space into rooms of different sizes. Heretofore it has been customary to out a groove in the wall and in the ceiling when a masonry partition is 5 to be built. In partitions of this kind various forms of bricks, hollow blocks and the like may be used. However, it has been the practice of late to use blocks formed. with gypsum as they are sufficiently strong and yet are very light. In

addition, they are substantially soundproof and will readily receive plaster. In the present invention the tie is adapted to be used with a wall of this kind to secure or lock the same to a vertical wall or a ceiling or bore if desired.

As illustrated in the drawing, the wall I is made of any desired number of blocks 2 with the mortar 3 used in the usual manner.

It will be noted that the blocks 2 are all provided with various notches or grooves 4 for the reception of plaster or mortar for connecting the blocks together.

As shown in Fig. 2, the mortar 5 interlooks with the block 2 and also with a metal tie strip 6 which is secured by nails or other means 'i to the wall 8. In this way the partition is secured or locked to the wall 8. The tie strip 6 is shown in detail in Fig. 3, from which it will be seen that this strip is made from foraminous sheet metal having salvaged edges 9 and lil. Through some of the openings in the strip the nails or other securing members I extend and project into the wall or ceiling 2 as the case may be.

From Fig. 2 it will also be noted that the strip 6 is provided with a bead or raised central portion H which extends the full length centrally of the strip and bulges outwardly so that the mortar 5 may completely surround or submerge the raised portion II as well as enter into the grooves 4.

Preferably the strip 6 is approximately as wide as the thickness of the brick 2 so that when the plaster i2 is applied, not only will the brick 2 be covered but also the ceiling strip and the mortar 5.

I claim:

1. The combination with a wall or ceiling and a partition, of a foraminous strip, means for securing said strip in position, and a filling of mortar interlocking with said partition and with said strip for binding the partition to the wall or ceiling.
